Pembrolizumab Versus Placebo Following Surgery and Radiation in Participants With Locally Advanced Cutaneous Squamous Cell Carcinoma (MK-3475-630 / KEYNOTE-630)

This is a randomized, double-blind, study that compares pembrolizumab with placebo given as adjuvant therapy in participants with high-risk locally advanced cutaneous squamous cell carcinoma (LA cSCC) that have undergone surgery with curative intent in combination with radiotherapy. The primary hypothesis is that pembrolizumab is superior to placebo in increasing recurrence free survival (RFS).

Has histologically confirmed LA cSCC with ?1 high-risk feature(s) as the primary site of malignancy

Has undergone complete macroscopic resection of all known cSCC disease with or without microscopic positive margins. For those participants with residual microscopic positive margin involvement, confirmation that additional re-excision is not possible must be provided

Has completed adjuvant radiotherapy (RT) for LA cSCC with last dose of RT ?4 weeks and ?16 weeks from randomization

Is disease free as assessed by the investigator with complete radiographic staging assessment ?28 days from randomization

Is not pregnant or breastfeeding

Is not a woman of childbearing potential (WOCBP)

Has a negative pregnancy test ?72 hours before the first dose of study intervention

Has provided an archival or newly-obtained tumor tissue sample adequate for Programmed Cell Death Ligand 1 (PD-L1) testing as determined by central laboratory testing

Has a life expectancy of >3 months

Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 ?10 days prior to the first dose of study intervention



Exclusion Criteria:

Has macroscopic residual cSCC after surgery and/or recurrence with active cSCC disease before randomization

Has any other histologic type of skin cancer other than invasive cSCC (eg, basal cell carcinoma) that has not been definitively treated with surgery or radiation; Bowen's disease; Merkel cell carcinoma; or melanoma

Has received prior therapy with an anti-programmed cell death receptor 1(PD-1), anti- PD-L1, or anti-programmed cell death receptor ligand 2 (PD-L2) agent or with an agent directed to another co-stimulatory or co-inhibitory T-cell receptor (eg, cytotoxic T-lymphocyte-associated protein 4 [CTLA-4], OX-40, CD137)

Has received prior systemic anticancer therapy including investigational agents for cSCC ?4 weeks prior to randomization

Has not recovered from all radiation-related toxicities and has not had radiation pneumonitis

Has received a live vaccine ?30 days prior to the first dose of study intervention

Is currently participating in or has participated in a study of an investigational agent or has used an investigational device ?4 weeks prior to the first dose of study intervention

Has an active autoimmune disease that has required systemic treatment in past 2 years (ie, with use of disease modifying agents, corticosteroids or immunosuppressive drugs)

Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis

Has an active infection requiring systemic therapy

Has a known history of human immunodeficiency virus (HIV) infection

Has a known history of hepatitis B (defined as hepatitis B surface antigen [HBsAg] reactive) or known active hepatitis C virus (HCV; defined as HCV RNA [qualitative] is detected) infection

Is pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 120 days after the last dose of study intervention

Has had an allogeneic tissue/solid organ transplant
